Answer:

y = x + 2

Step-by-step explanation:

The slope is 1

The y-intercept is 2

Answer: y=2x+0

Step-by-step explanation:

Answer:

Step-by-step explanation:

y=-1/13x   since it is perpendicular flip it and make it negative

Answer:

y = -1/13x + 27/13

Step-by-step explanation:

A perpendicular line will have the opposite reciprocal and sign.

So the perpendicular line slope to y = 13x + 4 would be -1/13

NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT

2 = -1/13(1) + b (b represents the y- intercept)

2 = -1/13 + b (add 1/13 to both sides)

y = -1/13x + 27/13 is the perpendicular line.

Answer:

side            -          equation       -         measurement

1st side       -           2s - 65         -                  55cm

2nd side     -               s               -                  60cm

3rd side      -            s - 10           -                  50cm

Step-by-step explanation:

total = 165

side - s

1st side = 2s - 65

2nd side = s

3rd side = s - 10

1st side + second side + 3rd side = 165

2s - 65 + s + s - 10 = 165

2s + s + s - 65 - 10 = 165

4s - 75 = 165

4s = 165+ 75

4s = 240

s = 60

1st side = 2s - 65

            = 2(60) - 65

            = 120 - 65

            = 55cm

2nd side = s

               = 60cm

3rd side = s - 10

              = 60 - 10

              = 50cm

3rd side is represented by s - 10 as it is less than the second side by 10cm hence taking away the 10 from the side forming the equation s - 10

Answer:

s-10

Step-by-step explanation:

Answer:

24 pounds of apples for $60

about 3 apples per pound

about 72 apples for $60

Step-by-step explanation:

$15 times 4 = $60, therefore 6 pounds times 4 = 24 pounds

5 out of 16 ounces equals about 3 apples per pound

24 pounds, with 3 apples in each pound, equals 72

Answer:

57,585

Step-by-step explanation:

55,000.x4.7%=2585.

55000.+2585=57,585

Answer:

$57,337.50

Step-by-step explanation:

In order to get the answer we would have to add 55, 000 and 4 [tex]\frac{1}{4}[/tex]% of 55,000 (because of the interest rate). In order to find 4 [tex]\frac{1}{4}[/tex] % we would have to multiply 55, 000 by 0,0425. So now we get the following.

Total cost of the loan = 55,000 + 55,000 x 0.0425 = 55,000 + 2,337.5 =

57,337.5

Answer:

25/3

Step-by-step explanation:

Set the equations equal to each other since the lines are parallel.

(x+20)=(4x-5)

-x  +5       -x   +5

25/3 = 3x/3

x = 25/3

Answer:

y=2x+1

Step-by-step explanation:

Input X=2 into the function, so y=2(2)+1, which is 5. This matches the table.

Answer:

It's the first one: y= 2x +1

Step-by-step explanation:

If you multiply 2 by 2, you'll get 4. then you add 1. You'll get 5.

same with the others-

Answer:

43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)

38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)

19 is what goes in the box

Answer:

A: The Twelve Oaks farm has 14 sheep and 2 acres of land.

Step-by-step explanation:

For every 7 sheep, there has to be one acre of land. In order for you to find how many sheep are needed for each acre, you would multiply the amount of acres and you should get the amount of sheep that farm holds.

A. 2 x 7 = 14 meaning there should be only 14 sheep at a farm that only has 2 acres of land.

B. 3 x 7 = 21 meaning there should be only 21 sheep at a farm that only has acres of land.

C. 6 x 7 = 42 meaning there should be only 42 sheep at a farm that only has 6 acres of land.

D. 2 x 7 = 14 meaning there should be only 14 sheep at a farm that only has 2 acres of land.

Hope this helps!

Answer:

Length of the fence required = 135 m

Step-by-step explanation:

Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid

Perimeter of ABCD = AB + BC + CD + AD

Since, AB = BC = EF = ED = 25 m

From the given right triangle BEC,

m∠EBC = m∠ECB = 45°

ΔBEC will be an isosceles triangle.

So, BE = EC

By Pythagoras theorem,

BC² = BE² + EC²

25² = 2(EC)²

EC = [tex]\frac{25}{\sqrt{2}} =17.7[/tex] m

And DC = (DF + EF + EC)

             = EC + EF + EC [Since, DF = EC]

             = 2EC + EF

             = 35.4 + 25

             = 60.4 m                            

Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25

                                              = 135.4 m

                                              ≈ 135 m

Therefore, length of the fence required = 132 m

Answer:

for every 7 miles Nolan drove alexander drove 1

Step-by-step explanation:

Answer:

19 years

Step-by-step explanation:

Initial height of tree when Samiya bought the tree = 3 inches

Growth in the height of tree every year = 5 inches

Number of years = [tex]y[/tex]

Growth in the height of tree in [tex]y[/tex] years = 5 inches multiplied by number of years

Growth in the height of tree in [tex]y[/tex] years = 5[tex]y[/tex] inches

To find:

Number of years taken by the tree to be 8 ft or 96 inches.

Solution:

The equation for height of tree after [tex]y[/tex] years can be written as:

3 + 5[tex]y[/tex] which is to be compared with 96 inches.

Therefore, the equation is:

[tex]3 + 5y = 96\\\Rightarrow 5y=93\\\Rightarrow y \approx 19[/tex]

Therefore, it will take 19 years for the tree to reach a height of 96 inches.

Answer:

The maximum a person can weigh to go on the ride safely is 100.5 kg

Step-by-step explanation:

The specification for the maximum weight of each person that goes on the ride = 100 kg

Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;

[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg

Answer:

2/15

Step-by-step explanation:

Step one:

given data

sample space

1 elephant,

4 bears,

3 cats, and

2 dogs.

sample size= 1+4+3+2= 10

Required:

By selecting without replacement, the probability that she chooses a bear both times

Step two:

the first event= Pr(bear)= 4/10= 2/5

the second event, the sample size is now 9 and the number of bears is now 3

Pr(bear)= 3/9= 1/3

Hence, the probability that she chooses a bear both times

= 2/5*1/3

=2/15
